Nez Perce soil series
A representative soil profile of the Nez Perce series. Nez Perce soils are on loess-covered hills and basalt plateaus at elevations of 2,600 to 4,100 feet. They formed in loess, although the lower part may be formed in material weathered from the underlying basalt. The climate is subhumid with peak precipitation is in May and June and minimum precipitation in July and August.
The Nez Perce series consists of very deep, moderately well drained soils that formed mainly in loess. Nez Perce soils are on loess-covered basalt plateaus and have slopes of 0 to 25 percent. The average annual precipitation is about 21 inches. The average annual temperature is about 45 degrees F.
TAXONOMIC CLASS: Fine, smectitic, mesic Xeric Argialbolls
Mollic epipedon thickness - 12 to 20 inches
Organic matter content in mollic epipedon (weighted average) - 3 to 6 percent
Depth to perched seasonal water table - 12 to 30 inches
Depth to argillic horizon - 14 to 27 inches
Depth to secondary lime - 20 to 40 inches
Some pedons have few basalt gravel and cobble throughout; however, the rock fragments are usually below the albic horizon
Average annual soil temperature - 47 to 50 degrees F
Average summer soil temperature - 60 to 65 degrees F
Particle-size control section (weighted average)
Clay content - 35 to 55 percent
USE AND VEGETATION: Soils are cultivated. Winter wheat, winter peas, barley, hay, and pasture are the principal crops. The natural vegetation is mainly Idaho fescue, bluebunch wheatgrass, sticky geranium, silky lupine, and arrowleaf balsamroot.
DISTRIBUTION AND EXTENT: Northern Idaho and eastern Washington. The series is extensive.
